Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge dewatering technology, specifically to a sludge recycling and dewatering device. Background Technology
[0002] Sludge recycling and dewatering is a key step in the wastewater treatment process. It aims to reduce the water content of sludge, reduce its volume and weight through physical, chemical or mechanical means, so as to facilitate subsequent disposal (such as resource utilization, landfill or incineration), while recovering useful substances (such as water, organic matter, heavy metals, etc.).
[0003] Chinese Patent Publication No. CN222781518U discloses a high-efficiency sludge dewatering device, including a housing with a dewatering barrel inside. The dewatering barrel is inclined and rotates within the housing. Multiple filter holes are provided on the surface of the dewatering barrel. A rotating mechanism for rotating the dewatering barrel is provided on the surface of the housing. A discharge box is installed at the higher end of the housing near the dewatering barrel, and a connecting box is installed at the lower end of the housing near the dewatering barrel. A discharge mechanism is provided inside the connecting box. Multiple drain pipes are installed on the surface of the housing, and a cleaning mechanism is provided inside the housing. This invention, through the design of the dewatering barrel, allows for rapid rotation of the sludge during transport, generating centrifugal force to remove moisture from the sludge and simultaneously cleaning the inner wall of the dewatering barrel, preventing sludge from adhering to the inside of the barrel.
[0004] In the aforementioned prior art, sludge can be added to a dewatering tank when dewatering. By controlling the rotation of the dewatering tank, centrifugal force can be used to achieve the dewatering effect of the sludge. However, the direction of sludge transport is relatively unidirectional. If the sludge moisture content is uneven, sludge with low moisture content may be stuck due to high friction, resulting in local accumulation. Uneven distribution will lead to incomplete dewatering and affect the dewatering effect. Utility Model Content
[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a sludge recycling and dewatering device, which solves the problems mentioned in the background art where the sludge dewatering device has a relatively unidirectional sludge conveying direction, and if the sludge moisture content is uneven, it is easy to cause local accumulation. Uneven distribution will lead to incomplete dewatering and affect the dewatering effect.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A sludge recycling and dewatering device, comprising:
[0008] Support frame;
[0009] A rotating structure, located inside the support frame, is used to drive the sludge to rotate and dewater.
[0010] A conveying structure, arranged on a support frame, is used in conjunction with the rotating structure to uniformly convey sludge into the rotating structure.
[0011] A movable structure, arranged on the conveying structure, is used to control the horizontal movement of the conveying structure.
[0012] Preferably, the rotating structure includes:
[0013] The supporting shell is arranged on the support frame;
[0014] The dehydration drum is rotatably installed inside the supporting shell;
[0015] The linkage gear ring is located on one side of the dehydration tank;
[0016] The drive motor is mounted on the support frame;
[0017] The linkage gear is located on the output end of the drive motor and meshes with the linkage gear ring;
[0018] The water outlet is located on the supporting shell.
[0019] Preferably, the rotating structure further includes:
[0020] Several limiting shafts are arranged on the inner wall of the supporting shell;
[0021] Two support rollers are rotatably mounted on corresponding limit shafts;
[0022] Two support rings are symmetrically fitted onto the dehydration tank, and each support ring is in contact with a corresponding support roller.
[0023] Preferably, the conveying structure includes:
[0024] The separator is movably installed inside the dehydration tank;
[0025] A support plate is arranged on one side of the partition cylinder;
[0026] The sludge conveying pipe is arranged inside the support plate;
[0027] Several branch pipes are evenly arranged on the sludge conveying pipe and connected to the sludge conveying pipe.
[0028] Several connecting holes are evenly distributed inside the partition cylinder and connected to the distribution pipe;
[0029] The sludge suction pump is located on one side of the support plate, and the conveying end of the sludge suction pump is located on the sludge conveying pipe.
[0030] Preferably, the conveying structure further includes several partition rings, which are evenly fitted on the partition cylinder to separate the internal space of the dehydration tank, and the connecting hole is located between two adjacent partition rings.
[0031] Preferably, the moving structure includes:
[0032] L-shaped brackets are arranged on one side of the support plate;
[0033] The movable motor is positioned on one side of the L-shaped bracket;
[0034] The casters are located at the output end of the motion motor;
[0035] The receiving assembly, located on one side of the support plate, is used to receive the dewatered sludge.
[0036] Preferably, the receiving assembly includes:
[0037] The receiving box is located on one side of the support plate and below the support shell;
[0038] Two pulley frames are symmetrically arranged on both sides of the receiving box;
[0039] Two guide pulleys are rotatably mounted on two pulley brackets.
[0040] Preferably, the receiving assembly further includes two guide grooves, which are symmetrically opened inside the support frame, and two guide pulleys are respectively movably installed in the two guide grooves.
[0041] The beneficial effects of this utility model are as follows:
[0042] This invention utilizes a sludge suction pump to draw sludge into a sludge delivery pipe, which then distributes it through several diversion pipes into a dewatering tank located between two partition rings. This ensures the sludge is evenly distributed within the dewatering tank. Activating the drive motor rotates the dewatering tank, allowing the sludge to be dewatered under centrifugal force. The partition rings separate the internal space of the dewatering tank, ensuring a uniform distribution of sludge during rotation. This allows centrifugal force to act more evenly on all the sludge, preventing localized over-thickness that could lead to insufficient dewatering.
[0043] This invention allows the support plate to move by activating a moving motor, which in turn moves the separator cylinder and separator ring out of the dewatering tank. During this process, the separator ring carries out the dewatered sludge, while the receiving box moves with the support plate to collect the sludge, facilitating the discharge of the dewatered sludge.

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0054] Example 1:
[0055] like Figures 1 to 6 As shown, this utility model provides a sludge recycling and dewatering device, including: a support frame 1 and a rotating structure arranged inside the support frame 1 for driving the sludge to rotate and dewater.
[0056] The rotating structure includes a support shell 2 arranged on a support frame 1, a dewatering tank 201 rotatably installed inside the support shell 2, a linkage gear ring 202 arranged on one side of the dewatering tank 201, a drive motor 203 arranged on the support frame 1, a linkage gear 204 arranged on the output end of the drive motor 203 and meshing with the linkage gear ring 202, and a water outlet 205 opened on the support shell 2. The drive motor 203 is turned on to drive the linkage gear 204 to rotate. When the linkage gear 204 rotates, it can drive the dewatering tank 201 to rotate through meshing with the linkage gear ring 202. Under the continuous rotation of the dewatering tank 201, the sludge can be dewatered under the action of centrifugal force.
[0057] The rotating structure also includes several limiting shafts 206 arranged on the inner wall of the supporting shell 2, two supporting rollers 207 rotatably sleeved on the corresponding limiting shafts 206, and two supporting rings 208 symmetrically sleeved on the dehydration drum 201. The two supporting rings 208 are in contact with the corresponding supporting rollers 207. When the dehydration drum 201 rotates, it can drive the supporting rings 208 to rotate, thereby causing the supporting rings 208 to drive the supporting rollers 207 to rotate on the limiting shafts 206 through the friction between the supporting rings 208 and the supporting rollers 207. The setting of the supporting rollers 207 can provide support for the dehydration drum 201 and make the rotation of the dehydration drum 201 smoother.
[0058] Example 2:
[0059] Based on Example 1, in order to ensure that the sludge is evenly distributed in the dewatering tank 201, a conveying structure for evenly conveying the sludge into the rotating structure is arranged on the support frame 1.
[0060] The conveying structure includes a partition cylinder 3 movably installed inside the dewatering tank 201, a support plate 301 arranged on one side of the partition cylinder 3, a sludge conveying pipe 302 arranged inside the support plate 301, several diversion pipes 303 evenly arranged on and connected to the sludge conveying pipe 302, several connecting holes 304 evenly opened inside the partition cylinder 3 and connected to the diversion pipes 303, and a sludge suction pump 305 arranged on one side of the support plate 301. The conveying end of the sludge suction pump 305 is arranged on the sludge conveying pipe 302. By turning on the sludge suction pump 305, sludge is sucked up and conveyed to the sludge conveying pipe 302 and then to the connecting holes 304 through the diversion pipes 303, so that the sludge can be evenly distributed in the dewatering tank 201.
[0061] The conveying structure also includes several partition rings 306 evenly fitted on the partition cylinder 3 to separate the internal space of the dewatering tank 201. The connecting hole 304 is located between two adjacent partition rings 306. Sludge will enter between the two partition rings 306 through the connecting hole 304. The internal space of the dewatering tank 201 can be separated by the arrangement of several partition rings 306.
[0062] Example 3:
[0063] Based on Example 1, in order to remove the dewatered sludge from the dewatering tank 201, a moving structure for controlling the horizontal movement of the conveying structure is arranged on the conveying structure.
[0064] The movable structure includes an L-shaped bracket 4 arranged on one side of the support plate 301, a movable motor 401 arranged on one side of the L-shaped bracket 4, a movable wheel 402 arranged on the output end of the movable motor 401, and a receiving component arranged on one side of the support plate 301 for receiving the dewatered sludge. The movable motor 401 is turned on to drive the movable wheel 402 to rotate, thereby driving the support plate 301 to move. When the support plate 301 moves, it can drive the separator cylinder 3 and the separator ring 306 to move out of the dewatering tank 201, which can carry out the sludge in the dewatering tank 201.
[0065] The receiving assembly includes a receiving box 403 arranged on one side of the support plate 301 and located below the support housing 2, two pulley frames 404 symmetrically arranged on both sides of the receiving box 403, and two guide pulleys 405 rotatably installed on the two pulley frames 404 respectively. When the support plate 301 moves, it will drive the receiving box 403 to move, so that the receiving box 403 moves out from below the support housing 2 to receive the sludge brought out.
[0066] Specifically, the receiving assembly also includes two guide grooves 406 symmetrically opened inside the support frame 1, and two guide pulleys 405 are respectively movably installed in the two guide grooves 406. When the receiving box 403 moves, it will drive the guide pulleys 405 to roll in the guide grooves 406 through the pulley frame 404. The setting of the guide grooves 406 can prevent the receiving box 403 from deviating in direction.
[0067] Working principle:
[0068] In use, the suction end of the sludge suction pump 305 is placed in the sludge. The sludge is then suctioned by turning on the sludge suction pump 305, and transported to the sludge conveying pipe 302 and then diverted to the diversion pipe 303. The sludge will enter between the two separating rings 306 through the connecting hole 304, so that the sludge can be evenly distributed in the dewatering tank 201. Then, the drive motor 203 is turned on to drive the linkage gear 204 to rotate. When the linkage gear 204 rotates, it can drive the dewatering tank 201 to rotate through meshing with the linkage gear ring 202. Under the continuous rotation of the dewatering tank 201, the sludge can be dewatered under the action of centrifugal force. The dewatered water will be discharged through the outlet 205. The space inside the dewatering tank 201 can be separated by the setting of several separating rings 306 to prevent sludge from accumulating in one place.
[0069] After dehydration is complete, the moving motor 401 can be turned on to drive the moving wheel 402 to rotate, which in turn drives the support plate 301 to move horizontally. When the support plate 301 moves, it can drive the separator cylinder 3 and the separator ring 306 to move out of the dehydration tank 201. Then, under the drive of the separator ring 306, the sludge in the dehydration tank 201 can be carried out. At the same time, the support plate 301 will drive the receiving box 403 to move, which can then drive the receiving box 403 to move out from under the support shell 2 to collect the sludge carried out.
[0070] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
